In order to keep the above objects, features, and advantages of the application more obvious and easy to understand, with reference to the accompanying drawing and specifically
The present application will be further described in detail for embodiment.
As shown in Figure 1, being a kind of flow chart of plane monitoring-network embodiment of the method provided by the present application, it should be noted that
About object to be checked in application documents, the application will be illustrated by taking cathode plate as an example, but object to be checked is not limited to cathode
Plate can also be that other planar objects, the application no longer illustrate one by one herein.Based on this, detection method provided in this embodiment
It may comprise steps of:
Step S110: it is transmitted in Object Process to be checked in transport mechanism, passes through multiple biographies equally distributed in detection device
Sensor detects the distance between the object to be checked and this multiple sensor.
In practical applications, the generating process of electrolysis industry is usually all continuous productive process, so, cathode plate to be checked (i.e. to
Inspection object) it will constantly be transported by chain car light transport mechanism, in cathode plate transportational process to be checked, the application can pass through inspection
It surveys device to detect it, specifically, by being uniformly arranged multiple sensors (A~I in such as Fig. 2 on detection means
This 9 sensors, the application are not construed as limiting the quantity of sensor) come detect cathode plate to be checked 201 and this multiple sensor it
Between distance.
Based on this, as shown in Fig. 2, the distance that detection device obtains be actually multiple sensors in the detection device with
The distance between corresponding position (i.e. A1~I1 in Fig. 2) on object to be checked, can be denoted as AA1, BB1, CC1, DD1, EE1,
FF1, GG1, HH1 and II1.
Step S120: utilizing neutrality line theorem, carries out to the distance between the object to be checked and the multiple sensor
It calculates.
Wherein, the application neutrality line theorem can be trapezoidal neutrality line theorem, i.e., will connect the line segment at trapezoidal two waist midpoint
It is called trapezoidal neutrality line, trapezoidal neutrality line is parallel to two bottoms, and is equal to the half of two bottom sums.
It is still illustrated by taking 9 sensors shown in Fig. 2 as an example, since 9 tactility apparatus in the Fig. 2 are uniformly arranged in 3x3
Column, obtain object to be checked between multiple sensors at a distance from after, due to three sensors being located along the same line and
Its on object to be checked corresponding position connection after will be formed one it is trapezoidal, so, the application can use neutrality line be equal to ladder
The half of two bottom edge sum of shape, i.e. (upper bottom edge+bottom)=2 neutrality lines, calculate be formed by trapezoidal two bottom edges and with
And 2 times of neutrality line values, i.e. calculating AA1+CC1,2BB1, DD1+FF1,2EE1, GG1+II1,2HH1, AA1+GG1,
2DD1, BB1+HH1,2EE1, CC1+II1,2FF1, AA1+II1,2EE1 and CC1+GG1, wherein XX1 indicates to pass
The distance between sensor X and checked object corresponding position X1 or length, X can be A~I.
Certainly, due to " upper bottom edge+bottom=2 neutrality lines ", this calculation formula can be deformed into " (in bottom-
Bit line)-(neutrality line-upper bottom edge)=0 ", thus, obtain object to be checked between multiple sensors at a distance from after, this
Application can also calculate obtained each distance value according to this deformed calculation formula, i.e., on same straight line
The corresponding linear distance between checked object of three sensors, successively calculate two neighboring sensor it is corresponding with it is tested
Then the difference of linear distance between object asks poor to two differences of gained again.
Based on this, since multiple sensors are to be uniformly distributed and be generally aligned in the same plane, if the detection plane bend of checked object
Curvature is all 0, that is to say, that each test point of checked object is on same plane, then, it arbitrarily takes on same straight line
Three sensor points and its point of corresponding position is formed by figure on checked object, should theoretically comply fully with
Trapezoidal neutrality line theorem meets above-mentioned (bottom-neutrality line)-(neutrality line-upper bottom edge)=0 this calculation formula.
However, in practical applications, the plane of the object to be checked such as cathode plate produced under normal conditions is all unable to get reason
Think state, i.e., plane bend curvature be zero state, so, be that its plane is allowed to have in the case where not influencing object to be checked application
Certain curvature, that is, camber, such as allows cathode plate with the error of the camber of 5mm, but it is not limited to this, specifically can basis
The actual needs of object to be checked determines, that is to say, that the application to object to be checked it is default can not the specific value of range do not make
It limits.
It can be seen that in practical applications, the figure obtained in the manner described above might not comply fully with trapezoidal middle position
Line theorem, that is to say, that above-mentioned formula (bottom-neutrality line)-(neutrality line-upper bottom edge) final result is not necessarily 0,
But as long as it can not can think that the plane bend curvature of object to be checked is qualified in range default.
By taking sensors A, B and the place C straight line in Fig. 2 as an example, it can be formed in the manner described above by A-B-C-C1-B1-A1
For figure, according to trapezoidal neutrality line theorem, calculating (AA1-BB1)-(BB1-CC1), (certainly, the application can also calculate (AA1
+ CC1) -2BB1's as a result, the application is not construed as limiting this) result.Based on this, 3x3 is provided that when detection device is above-mentioned
When 9 sensors of arrangement, above-mentioned steps S120 may include:
Select the distance between corresponding position of be located along the same line three sensors and object to be checked as target
Straight line；Calculating is collinear positioned at the numerical value of corresponding two target lines of sensor at same straight line both ends and with this is located at
Difference between the intermediate corresponding target line of sensor, i.e., calculated: (DD1-EE1)-(EE1- according to following formula
FF1)；(GG1-HH1)-(HH1-II1)；(AA1-DD1)-(DD1-GG1)；(BB1-EE1)-(EE1-HH1), (CC1-FF1)-
(FF1-II1), (AA1-EE1)-(EE1-II1), (CC1-EE1)-(EE1-GG1).
It should be noted that about the explanation that foregoing description is only carried out so that 9 sensors are arranged in detection device as an example, but simultaneously
It is not limited to this example, after number of sensors changes, identical in the manner described above can be adjusted in calculative
Hold, the application is no longer described in detail one by one herein, in order to make full use of neutrality line theorem, generally can not select to be not located at same
Four sensors on straight line are calculated in the manner described above.
Moreover, in above-described embodiment, three sensors that selection is located along the same line are not necessarily to, it can also be with
Be it is selected be not located at three sensors of same straight line, but the distance between itself and checked object straight line can be same flat
Face projects into trapezoidal pattern, can still be calculated at this time using aforesaid way, such as: can choose A, E and G in Fig. 2 this
Three sensors, as shown in figure 3, this apart from linear projection to AA1 and GG1 in the plane can be E by EE1’E1’, at this point,
(AA1-E can be calculated according to above-mentioned calculation formula using neutrality line theorem’E1’)-(E’E1’-GG1)；Similarly, the application is gone back
Can choose these three sensors of A, C and E, these three sensors of C, E and I, these three sensors of G, E and I etc. are calculated,
The application will not enumerate herein.
Step S130: being based on calculated result and default error range, rejects the underproof object to be checked of plane bend curvature.
As described above, default error range can be according to detected object concrete property to be checked and its job requirement etc.
Factor setting, the application do not limit its specific value, so, the application can verify selection at this time and different straight lines is selected to calculate
Whether obtained multiple differences (i.e. the calculated result of above-mentioned formula) are more than default error range, if this multiple difference is more than
Default error range, can determine that the plane bend curvature of the object to be checked is unqualified, that is to say, that the checked object is unqualified, no
It can enter follow-up link, the application can use device for eliminating for its automatic rejection, be not necessarily to manual sorting.
Wherein, it is still illustrated so that object to be checked is cathode plate as an example, at this point, above-mentioned default error range can be with are as follows: no
Greater than 5mm and it is not less than -5mm, then, simultaneously whether plane monitoring-network mode as described above may determine that following formula
It sets up:
-5mm≤(AA1-BB1)-(BB1-CC1)≤5mm；-5mm≤(DD1-EE1)-(EE1-FF1)≤5mm；-5mm≤
(GG1-HH1)-(HH1-II1)≤5mm；-5mm≤(AA1-DD1)-(DD1-GG1)≤5mm；-5mm≤(BB1-EE1)-(EE1-
HH1)≤5mm；-5mm≤(CC1-FF1)-(FF1-II1)≤5mm；-5mm≤(AA1-EE1)-(EE1-II1)≤5mm；-5mm
≤(CC1-EE1)-(EE1-GG1)≤5mm。
In the present embodiment practical application, when above-mentioned 8 judgement formulas are set up simultaneously, illustrate the plain bending of object to be checked
Degree meets the requirements, and the checked object is qualified, can come into operation；Conversely, if there are invalid judgements in above-mentioned 8 judgement formulas
Formula illustrates that checked object plane bend curvature is unqualified, cannot come into operation, and the application will be by device for eliminating by this kind of quilt at this time
Object automatic rejection is examined, next destination will not be transported to again, it can be seen that, the application is not necessarily to artificial detection and sorts out do not conform to
Lattice checked object, greatly improves work efficiency, and reduces labour, and avoids leakage caused by due to artificial detect for a long time
The problems such as inspection and erroneous detection；Moreover, detection device volume used herein is smaller, carried convenient for staff.
It should be noted that for cathode plate plane monitoring-network, in conjunction with the description of above-mentioned calculating process, it is not limited to above-mentioned
8 judge formula, can also judge whether the result of other calculation formula of above-mentioned determination is more than default error range, and the application exists
This is no longer described in detail one by one.
As another embodiment of the application, due to the plane monitoring-network to object to be checked, need to reach inspection in the object to be checked
Device opposite is surveyed, multiple sensors in the detection device can just be made to detect that it arrives the distance of the object to be checked, so, upper
On the basis of stating each embodiment, flow chart as shown in Figure 4, the application can also include:
Step S401: the location information of object to be checked is detected.
In practical applications, inspection can be preset into the position that checked object is transported to detection device opposite by transport mechanism
Location is set, so, it, can be to the position of the checked object of transmission in order to guarantee the accuracy of testing result that detection device obtains
It being detected, the present embodiment can use multiple sensors in the detection device to detect the location information of checked object,
Other detection devices be can use to detect the change in location of checked object, the application is not construed as limiting this.
Step S402: utilizing the location information, determines whether object to be checked reaches default detection position, if so, executing step
Rapid S403；If it is not, return step S401.
The present embodiment can determine the suitable position for detecting object to be checked as default according to the current location of detection device
Detection position after detecting the location information of checked object, it can be compared with default detection position later, from
And determine whether the default detection position is suitable with the presence or absence of the current location of object to be checked and the object to be checked, to guarantee
Detection device checked object obtained reaches the accuracy of the distance of multiple sensors.
Wherein, the manner of comparison about the location information of checked object and default detection position, the application do not limit herein
It is fixed, as long as above-mentioned purpose can be reached.
Step S403: between the object to be checked and this multiple sensor that multiple sensors in receiving detection device detect
Distance.
In practical applications, due to being a kind of mechanical straight without being carried out with for example above-mentioned transport mechanism of moving component close to switch
Contact, it will be able to which the position switch of operation does not need Mechanical Contact when the sensitive surface of object proximity switch is to operating distance
And any pressure of application can make switch motion, so that drive dynamic control device provides control instruction.So the present embodiment is in determination
When object to be checked reaches default detection position, it can set out and be opened close to switch, later, trigger control device executes the step
S403, to guarantee the accuracy of the application plane monitoring-network.
